A trip brought about by the drug ketamine. It has somethings in common with OBE and astral travel, but often the person does not realise they are tripping or even anything about the reality they usualy frequent, it can be terrifying and twisted, a journey to pseudo enlightenment, a ten frame period of five minuets that repeat them selfs into eturnity or all of these things. It is truely an amasing experence that I can not liken to anything else I have experenced.
Not everyone who has done ketamine has experenced a k hole (as is evident from some of the other definitions), and the words k hole are often used to mean very ketamised and therefore unable to preform simple tasks or have a conversation.

I went in a k-hole flew over green feilds met some people I wouldn't meet in real life for another two months or so at a party, wondered how the fuck I was gonna get out of this circle then I realised that I am dead and death is just a transition and I am eturnal and I felt amasing and liberated. Five hours later I couldn't remember any of that.

The strangest feeling you will ever experience while on Ketamine. On your first k-hole, you may feel like you're dying, or that you are in fact not in control of your body. You will more than likely not remember even being in a k-hole the next day. After the first k-hole, you will find that you are able to enjoy being in one.

A drug slang term used to describe an "out-of-body" feeling induced by ketamine, or special k. This feeling cannot be controlled by the user and can happen unexpectedly. A ketamine user can be stuck in a k-hole but has control over it and basically has to ride out the experience.
